Which consequence results when rapid aggradation overwhelms stream incision within alluvial deposits?

💡 Explanation

Braided stream formation happens because decreased flow depth increases bed shear-stress, leading to multiple, unstable channels due to high sediment supply. Therefore, a braided network develops, rather than a single, sinuous channel owing to lateral migration.
